    摘要: The invention provides a solid phosphoric acid catalyst which has high activity and attains high dimer selectivity in olefin dimerization reactions and efficient methods of olefin dimerization. The solid phosphoric acid catalyst comprises a carrier and phosphoric acid supported thereon. When the solid phosphoric acid catalyst is heated at 250° C. for 20 minutes, heating loss of water is 50 mass % or more based on diphosphorus pentoxide (P2O5) derived from the phosphoric acid. A method of olefin dimerization comprises bringing an olefin-containing feed material containing water in an amount of 10-1000 mass ppm into contact with the catalyst to initiate the reaction.

    摘要: There is provided a process for producing acrolein from glycerin, exhibiting a suppressed decrease in the yield of acrolein with time. In the process for producing acrolein by dehydrating glycerin in the presence of a catalyst containing a metal phosphate, one, or two or more, metal phosphates are used, which are selected from aluminum salts, zirconium salts, manganese salts, alkali metal salts (provided that the alkali metal is sodium, potassium, or cesium, and the ratio between the mole number (M) of the alkali metal and the mole number (P) of phosphoric acid (i.e., M/P ratio) in the metal phosphate is 2.0 or lower), alkali earth metal salts (provided that the ratio between the mole number (M) of the alkali earth metal and the mole number (P) of phosphoric acid (i.e., M/P ratio) in the metal phosphate is 1.0 or lower), and the like.
